Developers and businesses need a reliable and cost-effective way to route end users to Internet applications.

Amazon Route 53

Amazon Route 53 is a highly available and scalable Domain Name System (DNS) web service. It is designed to give developers and businesses an extremely reliable and cost effective way to route end users to Internet applications by translating human readable names like http://www.example.com into the numeric IP addresses like 192.0.2.1 that computers use to connect to each other.

Need to plan the order in which Amazon Web Services will be provisioned, keeping in mind dependencies among the services.

AWS CloudFormation

AWS CloudFormation gives developers and systems administrators an easy way to create a collection of related AWS resources and provision them in an orderly and predictable fashion.

An Amazon Security Group lets you specify the protocols, ports, and source IP address ranges that are allowed to reach your Amazon EC2 instances.

Need to design with failover in mind.

Availability Zones

Availability Zones are distinct locations engineered to be insulated from failures in other Availability Zones. Each Availability Zone provides inexpensive, low latency network connectivity to other Availability Zones in the same region.
